Notes From A Criminal Investigation 7 Chapter 21

Qin Dongjiang said: "We need to clarify the process of the case. From the perspective of the files and the scene, I always feel that the whole process is a bit vague. Let's restore the whole case now. The first step is that Zhao Daijun and the murderer entered the room. Judging from the situation of the doors and windows, they entered peacefully, which means that the murderer and Zhao Daijun knew each other. The second step is that Zhao Daijun drank the water with the drug "Ren Woxing" and then fainted. The third step is how to control Zhao Daijun. It is another problem. If the murderer is a man and has a murder weapon, it will be easier to control Zhao Daijun. If the murderer is a woman, then she must take advantage of Zhao Daijun's coma to control Zhao Daijun and tie him up with a rope or other things. In this case, there should be traces on the body surface. However, the autopsy report did not find any traces of being tied up on Zhao Daijun's body surface. So I think the murderer's behavior is to knock on the head, burn the lower body when Zhao Daijun is comatose or dying, and take money. The cash is a spare fund for the car, and it will not be placed too secretly. The murderer burned the lower body to vent his anger, not to ask for money."

The murderer was able to use drugs, the dead body was naked and the sofa cover was messy, which meant that the murderer had close contact with Zhao Daijun. Taking away the cash, burning Zhao Daijun's lower body, and the dead body's skull was fractured by multiple blows, all these signs indicate that the murderer is a woman who has access to drugs, and more likely a woman who works in a bad job.

These are preliminary judgments and are consistent with the inferences of the Huzhou Criminal Police Detachment.

Owen did not rush to draw conclusions. He went to the Red Star Kindergarten with Jiang Keyang and Wu Xue to observe Yang Mei. Owen came from a grassroots criminal investigation unit and was used to doing things himself. Since he became the leader of the second special case team, he was not used to handing over the task of observing Yang Mei to the Huzhou investigators. He knew that what others saw was superficial, and he had to see it with his own eyes to know the truth.

When the kindergarten was dismissed, a graceful middle-aged woman appeared at the gate of the kindergarten. She greeted the parents who came to pick up their children with a smile. When the parents left with their children, they all waved to the middle-aged woman. The kindergarten dismissed the students in different classes. After the students in the small, medium and large classes left, the campus became quiet. The middle-aged woman talked to the teachers and security guards at the gate for a few words, then turned around and walked back to the school.
